摘　　要：以单相电机速度为控制对象,采用STC89C51单片机为控制核心,设计了一套单相电机调速器控制系统。系统采用锯齿波产生脉冲作为双向晶闸管的触发信号,通过控制双向晶闸管的导通角调节电机的端电压,从而实现电机调速。This paper utilized the speed regulator of Single-phase motors as a controlled object and STC89C51 single chip as control core to design a set of control system of single-phase motor governor. This system used pulse produced by the sawtooth wave as the trigger signal of bidirectional thyristor and achieved speed adjusting of the electrical machine by controlling the terminal voltage of conduction angle adjusting electrical machine of the bidirectional thyristor.
